Abstract
An anti-loosening lime nitrogen as chemical fertilizer is prepared through spraying the atomized liquid of additive onto lime nitrogen powder and fully stirring, and features high anti-loosening nature and adhesion, less loss during applying it and transportation, low toxic damage to people and animals and high utilization rate.
Description
Lime nitrogen also is calcium cyanamide or carbon CaCl2, and chemical formula CaCN is a kind of of cyanamide nitrogen fertilizer, is strong basicity, and suitable imposing in the acid soil has and improve the soil and defoliating agent or herbicide action, is widely used in paddy rice and silo crop.Lime nitrogen is toxic to people, animal and crop, only in being manured into soil, change into urea after, just become nontoxicly, contained nitrogen also could be by plant absorbing.Traditional lime nitrogen product is Powdered, and is big to the people, animal toxic action during fertilising, has wind weather dispensing fertilizer to fly away with the wind, loses bigger.
The purpose of this invention is to provide a kind of use and transporting procedures in, anti-scattered type lime nitrogen product that loss little little to the people, animal toxic action.
The present invention is achieved in that and gets certain quantity of additive, after the atomizer atomizing, sprays into the lime nitrogen powder of capacity, after sending into stirrer and stirring, sends into the wrapping machine packing, becomes anti-scattered type lime nitrogen product.
Advantage of the present invention is: the anti-scattered performance of (one) product is good, and strong adhesion is little to the people, animal toxic action in use and transporting procedures, and (two) loss is few, the fertilizer efficiency height.(3) production process is simple.
Accompanying drawing 1 is anti-scattered lime nitrogen manufacturing process flow diagram.
In conjunction with the embodiments the present invention is described below in detail: the tensio-active agent of 1-3% is added the 0.5-1.5% machinery oil, after the atomizer atomizing, spray into (about 92%) lime nitrogen powder of capacity, send into stirrer and stir, send into wrapping machine metering and packing.
In the raw material machinery oil is required: volatility is low, burning-point is high; Tensio-active agent is required: efficient, nontoxic.Packing of product bag is answered good seal performance.
Claims (2)
1, a kind of anti-scattered type lime nitrogen chemical fertilizer, it is characterized in that: it has anti-scattered performance, and its technological process of production is: get certain quantity of additive, after the atomizer atomizing, spray into the lime nitrogen powder of capacity, after sending into stirrer and stirring, send into the wrapping machine packing.
2, lime nitrogen chemical fertilizer as claimed in claim 1 is characterized in that: the additive in its batching is a certain proportion of tensio-active agent and machinery oil.
